ACCUMULATOR
DESCRIPTION
The 41te underdrive, overdrive, low/reverse, and
2/4 clutch hydraulic circuits each contain an accumu-
lator. An accumulator typically consists of a piston,
seals, return spring(s), and a cover or plug. The over-
drive and underdrive accumulators are located
within the transaxle case, and are retained by the
valve body (Fig. 172) .
The low reverse accumulator (Fig. 173) is also
located within the transaxle case, but the assembly is
retained by a cover and a snap-ring.
The 2/4 accumulator is located in the valve body. It
is retained by a cover and retaining screws (Fig. 174).

OPERATION
The function of an accumulator is to cushion the
application of a frictional clutch element. When pres-
surized fluid is applied to a clutch circuit, the appli-
cation force is dampened by fluid collecting in the
respective accumulator chamber against the piston
and spring(s). The intended result is a smooth, firm
clutch application.
AUTOSTICK SWITCH
DESCRIPTION
Autostick is a driver-interactive transaxle feature
that offers manual gear shifting capability. The con-
trol switch is part of the transaxle gear shift lever as
shown in (Fig. 175). It can only be serviced by replac-
ing the gearshift lever assembly. (Refer to 19 -
STEERING/COLUMN/GEAR SHIFT LEVER -
REMOVAL)
OPERATION
When the shift lever is moved into the Autostick
position (as indicated by the Shift Lever Position
Indicator in the cluster), the transaxle remains in
whatever gear it was using before Autostick was acti-
vated. The TCM sends a 5 volt signal through the
switch and then monitors the signal for voltage drop.
Each switch state (driver command) results in a spe-
cific voltage reading sensed by the TCM. The TCM
then determines transaxle operation (upshift/down-
shift/OD Lockout) based on their corresponding volt-
age. Refer to the following chart for corresponding
switch states and voltage readings:
Switch State Voltage Reading
Autostick DOWN
depressed0.3V-1.6V
Autostick UP depressed 1.6V-2.8V
Overdrive OFF9Lockout9
depressed2.8V-3.8V
All switches open 3.8V-4.8V
-Voltage values <.3V and >4.8V are considered
INVALID and will result in a DTC
Moving the switch up causes an upshift and mov-
ing the switch down causes a downshift. The instru-
ment cluster will illuminate the selected gear. The
vehicle can be launched in 1st, 2nd, or 3rd gear while
in the Autostick mode. The speed control is operable
